Sony Recalls NP-F550 and NP-F750 batteries

Sony Recalls NP-F550 and NP-F570 InfoLithium batteries
bought after March 1999 due to evidence of a very small percentage (3
out of 415,000) overheating and smoking during recharge, these batteries
are used on a variety of devices including the Sony Mavicas and D700 /
D770. If you've bought either of these InfoLithium batteries since March
1999 should check the dedicated Sony website or call a toll free number
(U.S.) to check their battery.
